In simple words, passive noise cancellation treatments are all about absorption and deflection. They are a barrier between the noise source and the observer. Passive treatments are like foam plugs in the ear, foam lining between the car engine and the interiors. Their main purpose is to both absorb the sound, and turn it into something different, or reflect it in another direction just like a noise reduction fence.
